I'm having a little bit of this right now too. AAS can do a lot of different t things to our libido and performance on cycle. I'm on Test/NPP/Dbol and had to quit after about 30 minutes of trying to get off over the weekend. I went like a rabbit the whole time and still couldn't get it and had to quit when I just got too worn out and winded and was dripping with sweat. I just laid back and had her jack me off the rest of the way. All Part of the game.
